noise_reduction
Remove background noise from audio recordings by applying noise reduction processing. First capture a noise profile from a silent section, then clean the desired audio selection.
Instructions
Apply noise reduction to the selected audio. You MUST call get_noise_profile first on a region of pure noise, then select the audio you want to clean, then call this.
WARNING: Values above 20 dB risk audible artifacts (warbling, metallic sound). Use 6-12 dB for gentle cleanup, 12-20 dB for moderate noise. Only exceed 20 dB for extremely noisy recordings where some artifact trade-off is acceptable.
Args: noise_reduction_db: Amount of noise reduction in dB (0-48). Default: 12 sensitivity: How sensitive the detection is (0-24). Default: 6 frequency_smoothing: Number of frequency smoothing bands (0-12). Default: 3
